How To Update Kindle Books on Your iPhone

So you've heard that your Kindle books are supposed to be automatically updated, but it doesn't seem to be happening. Let's get started correcting that issue!

Sync Your Devices With Whispersync

Whispersync for Books is enabled by default and allows devices to share content as long as they are registered under the same Amazon account. Make sure Whispersync is enabled on your account so that you don't lose your notes, highlights, and reading progress when switching between devices.

  • From the Kindle app, tap on Home in the lower right corner.
  • Now tap on Settings.

As you can see, the Kindle app doesn't include a setting for making sure the content of your books will be automatically updated, so now that you've made sure Whispersync is on, let's get started turning on your automatic updates.

  • Open a web browser on your iPhone or computer and log in to your Amazon account.
  • Tap on the icon next to your name.
